Cancels the specified payment before it is settled. The payment will be recorded as a void, but Clover may convert the void into a refund at the payment gateway under certain conditions. For final payments (where the final flag is set to true), a void cannot be processed outside of the settlement window (more than 25 minutes after the payment). When a void is not possible, Clover performs a refund instead of a void.
